Have you looked at the example configuration for USB Interface III
and DX4Win available in microHAM Router (Help | Download Documents)
or in the USB III area at www.microHAM-USA.com/support.html?   It
contains all of the settings necessary ...

Note - with DX4Win you *must* set the CW PTT to VOX and close the CW
Keyboard to release the CW/PTT port for use by MMTTY/EXTFSK for FSK
before you can open the MMTTY Window.  Simply closing the CW Keyboard
does not seem to release the PTT (RTS).

73,
